Model 1 is an age- and gender-adjusted ordinary least squares regression model (separate models for food security and cooking frequency).
Model 2 is an ordinary least squares model (separate models for food security and cooking frequency) adjusted for age, sex and gender, race and ethnicity, education, income, marital status, household size, presence of children aged younger than 18 years in the household, employment, Supplemental Nutrition Assistance Program participation, and student status.
Ref = reference category.
P for trend obtained using the postestimation contrast command in Stata41 to test whether or not the linear trend across categories is significant.
